Describes an undergraduate biochemistry experiment which involves the preparation and kinetics of an oxidation-reduction enzyme system, methemoglobin reductase. A crude enzyme extract is prepared and assayed spectrophotometrically. The enzyme system obeys Michaelis-Menton kinetics with respect to both substrate and the NADH cofactor. (MLH)

Gives highlights of two symposia on chemical education held in Madrid in September, 1975. Topics included the use of educational technology, teacher training, and curriculum. (MLH)

Describes an undergraduate chemistry experiment in which the concentration of chloride, fluoride, or bromide ions can be quantitatively determined by titrating with mercury (II) ions. (MLH)

Describes methods for teaching the mole concept, including analogous calculations involving household objects, and the use of a cardboard wheel showing the interrelationships between moles, molecular weight, and the gaseous molar volume. (MLH)

Describes a biochemistry laboratory course in which students worked in groups; each group selected three of nine possible experiments. Each student was responsible for using the chemical literature to obtain detailed procedures for performing the experiments, and submitted formal reports on each experiment. (MLH)

Explains the use of computer assisted graphic display to permit the questioning and testing of fundamental chemical relationships. Illustrates the operation of the technique in a simple equilibrium experiment. (GS)

Describes the teaching of drug interactions to a college science class, using supplementary literary and historical information provided by a literature professor. (MLH)

Suggests that some way be found to provide teaching jobs for chemistry Ph.D's whose main interest is chemical education. (MLH)

Describes how to construct an isothermal calorimeter and lists typical results of a displacement reaction using zinc. (LS)

Lists advantages of combining physics and chemistry into a three year physical science course. Cites increase in teacher morale and decrease in student disciplinary problems as two important results. (CP)
